Smart home energy savings - update for 2010

Here’s an updated graph showing the ongoing reduction in energy for our
smart home. Driven mainly by continual improvement in the algorithms
that control the heating, air conditioning and lighting the overall
consumption of gas and electricity has continued to decline throughout

It appears however that I am approaching the limit as to what is
possible as the trend lines are beginning to flatten out. Going forward
I’ll continue to try to improve the algorithms but I’ll also be on the
lookout for any parasitic power-consuming devices and I’ll be dealing
with them using techniques like the smart power strip I mentioned
here.
